<P>These pages track footprint and performance metrics for ACE+TAO.
The results are collected on one of our nightly regression tests.
The complete source for the tests is available as part of the
ACE+TAO
<A HREF="http://ace.cs.wustl.edu/Download.html">
distribution
</A>.
The hardware and software configuration used for these tests is
described <A HREF="configuration.shtml">here</A>.
Notice, however, that the results contained here may be
different from what you will obtain using a TAO release or beta
kit, since the experiments are based on our current source tree.
</P>
<P>More information about ACE+TAO footprints, and the continuing
effort to reduce the library and application's code size can be
found in the
<A HREF="http://ace.cs.wustl.edu/cvsweb/ace-latest.cgi/ACE_wrappers/docs/ACE-subsets.html">
ACE+TAO subsetting

page.

<H2>Performance Results</H2>
<P>ORB throughput, in requests per second,
using the performance test in:
<CODE>$ACE_ROOT/TAO/performance-tests/Single_Threaded_Latency</CODE>,
the ORB configuration is optimized for single threaded
applications using the <CODE>svc.conf</CODE> file in said
directory.
The test is executed over the loopback interface, using the
<CODE>run_test.pl</CODE> driver script in the same directory.
